/**
 * A helper for pastis-NB's fit (§25.6, `analysis/likelihoodThreads.ts`): its
 * MDS start, then its likelihood.
 *
 * Sent its bands' rows once per objective, and then a point per evaluation, it
 * computes its bands' values and gradients and sends them back
 * (`likelihoodHelper`). One fit per worker: the thread that started it terminates it when the fit ends, or
 * stops.
